Hello all, i have a hurco bmc4020 with ultimax 3 control. i download a bnc g code program from cam system with tool change
and spindle commands. then when i run the program it seems to skip spindle speed changes.
is this conflicting with the tool library settings?
thanks!

Which CAM system are you using to generate the g code? Post your g code here and I can take a look.

I'm not at the shop to verify but I use Bobcad and I have a BMC4020. Looking at your g code, if you remove the 0's and do T2 M6 M3 see if that does a tool change and turn the spindle on to 1000 RPM.

Thanks for the help. I found that I have to have the spindle speed
Before m03. Or it throws it off.
